Systems and methods for secure reprovisioning

ABSTRACT

Systems and methods for authentication may include a first device having an association with a first account, including a memory containing one or more applets, a counter value, and transmission data, a communication interface, and one or more processors in communication with the memory and communication interface. The first device may create a cryptogram based on the counter value, wherein the cryptogram includes the counter value and the transmission data. The first device may transmit, after entry of the communication interface into a communication field, the cryptogram, and update, after transmission of the cryptogram, the counter value. The first device may receive, via the communication interface, one or more encrypted keys and one or more parameters. The first device may decrypt the one or more encrypted keys and, after decryption of the one or more encrypted keys, switch an association from the first account to a second account.

FIELD OF THE DISCLOSURE

The present disclosure relates to systems and methods for secure reprovisioning, including the secure reprovisioning of contact-based cards and contactless cards.

BACKGROUND

Card-based transactions are becoming increasingly common. These transactions often involve the use of a card, such as a contact-based card or a contactless card, in communication with a point of sale device, a server, or other device. It is necessary to protect such communications from interception and unauthorized access. However, transmission of data is susceptible to phishing attacks and replay attacks, resulting in increased security risks and account or card misuse.

For contact-based cards, there is an increased security risk of card skimming which may further result in compromised security. Security risks may also be increased when using contactless cards, which communicate with other devices wirelessly. A contactless card using near field communication (NFC), Wi-Fi, or Bluetooth, for example, to transmit data encounters the risk that the data transmission will be intercepted or observed by an unauthorized or malicious reader.

If a security risk, misuse, unauthorized access, or other problem is encountered, reissuance of the card may be required. Reissuance of the card can further lead to security concerns, as malicious attackers may be aware of the original card, as well as the disruption of the ability of a user to engage in activity with the associated account. For example, a card that is mailed may be intercepted en route to a user and subject to misuse. Additionally, fraudulent actors may change the address such that the card is reissued to the address of their choice. Further, a card that has been mailed may be read contactlessly through the envelope and the card number may be skimmed.

These and other deficiencies exist. Accordingly, there is a need for systems and methods for authenticating secure card reprovisioning that overcome these deficiencies and results in a transition from a first account to a second account in a secure and reliable manner by protecting communications from interception and unauthorized access.

DETAILED DESCRIPTION

The following description of embodiments provides non-limiting representative examples referencing numerals to particularly describe features and teachings of different aspects of the invention. The embodiments described should be recognized as capable of implementation separately, or in combination, with other embodiments from the description of the embodiments. A person of ordinary skill in the art reviewing the description of embodiments should be able to learn and understand the different described aspects of the invention. The description of embodiments should facilitate understanding of the invention to such an extent that other implementations, not specifically covered but within the knowledge of a person of skill in the art having read the description of embodiments, would be understood to be consistent with an application of the invention.

Benefits of the systems and methods disclosed herein include improved security for authenticating secure card reprovisioning that results in a transition from a first account to a second account in a secure and reliable manner by protecting communications from interception and unauthorized access. The systems and methods disclosed herein allow for the avoidance of phishing attacks and preventing replay attacks, thereby increasing security. Security can also be increased by reducing the risks of other common attacks. For example, the systems and methods disclosed herein reduce the risk of card skimming attacks for contact-based cards and the risk of the unauthorized observance or interception of data transmissions for contactless cards through the use of encrypted data communications. As another example, the systems and methods disclosed herein provide for securely reprovisioning cards via multifactor authentication.

Accordingly, keys of cards may be securely generated, encrypted, and reissued, rather than collecting the cards, and programming each card for reissuance, thereby mitigating security risks, reducing costs, and improving transaction efficiency. These benefits may be achieved without inconveniencing the user or otherwise degrading the user experience with a reissuance process. This avoids disruption, reduces the time and costs associated with card reissuance processes, and allows the user to continue engaging in activity with the associated account. By having the card reissuance handled at an automated teller machine (ATM), authentication and controlled access to the ATM is more secure. As another benefit, the need to deliver cards through the mail can be reduced or eliminated, which improves security and reduces the risk of cards being intercepted in the mail, the risk of fraudulent manipulation of delivery addresses to redirect cards to incorrect or unauthorized addresses, and the risk of card number skimming of cards in the mail.

Accordingly, the systems and methods disclosed herein reduce the risk of fraudulent activity, such as misuse of the card or an account associated with the card, in a secure and unobtrusive manner that does not inconvenience the user.

In one example, one or more sets of first devices 105 may be prioritized to receive the one or more commands-application protocol data unit after the server 120 is configured to determine whether the first device 105 is a credit card and is associated with a notice of fraudulent charges. In another example, one or more sets of first devices 105 may be prioritized to receive the one or more commands-application protocol data unit after the server 120 is configured to determine whether the first device 105 is an identification card that has been abnormally used, for example exceeding a predetermined threshold, for one or more transactions. In yet another example, one or more sets of first device 105 may be prioritized to receive the one or more commands-application protocol data unit after the server 120 is configured to determine how much time has elapsed since issuance of the first device 105. In these non-limiting examples, the server 120 may be further configured to prioritize which of these determinations are to be made first, second, third, etc. In this manner, a designated number of first devices 105 may be reprovisioned on an individual basis and/or in a batch. The first devices 105 may also be reprovisioned on an as-needed basis, according to a predetermined schedule, and/or any combination thereof.

The first device 105 may be configured to receive the one or more commands-application protocol data unit. For example, the first device 105 may be configured to receive the one or more commands-application protocol data unit from the application 116 of the second device 110. The first device 105 may be configured to decrypt the one or more encrypted keys. One or more applets, such as applet 106, of the first device 105 may be configured to store one or more decrypted keys in a secure element. An applet 106, such as a first applet, may be configured to transmit, via a communication channel 111, the one or more decrypted keys and the one or more parameters to a second applet 109. After decryption of the one or more encrypted keys, the first device 105 may be configured to change an association from a first account to a second account. Moreover, the first device 105 may be restricted to a predetermined usage after decryption of the one or more encrypted keys. In one example, the first device 105 may be subject to one or more predetermined spending thresholds. In another example, the first device 105 may be subject to a predetermined number of uses. For example, the first device 105 may be used for only a designated set of transactions, such as for lunch only and/or for office furniture. In another example, the first device 105 may be subject to a predetermined number of usages for one or more types of transactions, including but not limited to a debit card transaction or a credit card transaction.

In another example, the first device 105 may be used for only transactions occurring during a certain time (e.g., business hours of 9:00 am to 5:00 pm), on certain days of the week (e.g., weekdays, weekends, only Mondays, only Thursdays and Fridays), of on a certain date (e.g., Wednesday, Jul. 1, 2020). In another example, the first device 105 may be used only for certain purposes, such as for expense account purposes (e.g., travel expenses including airfare, meals, and hotels), for a designated project (e.g., a certain type of equipment or hardware needed for a project), with designated or approved merchants, or with a specified list of merchants known to offer goods or services needed for a particular purposes.

It is understood that the foregoing listings are exemplary and that any of these examples can be used in combination with one another. Thus, a user may use the same card configured for a variety of purposes and with a variety of accounts.

The first device 105 may be configured to transmit, responsive to the one or more commands-application protocol data unit, one or more responses-application protocol data unit (R-APDU). The one or more responses-application protocol data unit may include one or bytes indicative of a status of the command. For example, at least one of the one or more responses-application protocol data unit may be configured to indicate an execution status associated with the one or more instructions. The first device 105 may be configured to transmit the one or more responses-application protocol data unit to the application 116 of the second device 110. In some examples, the first device 105 may be configured to return a successful execution status associated with the one or more instructions. To the extent that the execution status of the one or more instructions is not successful, the first device 105 may be configured to return a warning or unsuccessful execution status. For example, the one or more responses-application protocol data unit may be configured to indicate if and when the one or more encrypted keys were decrypted and/or if and when the one or more decrypted keys were stored.

The application 116 may be configured to receive the one or more responses-application protocol data unit from the first device 105. For example, the one or more responses-application protocol data unit may be received after one or more entries of the communication interface 107 into a communication field of the second device 110. The one or more entries may be associated with at least one selected from the group of a tap, a swipe, a wave, and/or any combination thereof. Depending on the results of the execution status of the one or more instructions, the application 116 may be configured to take one or more corrective actions. In one example, the application 116 may be configured to re-send the one or more commands-application protocol data unit if the execution status of the one or more instructions is unsuccessful.

In other examples, the server may be configured to authenticate the input based on one or more requests transmitted from the application to the server.

At block 615, the method 600 may include prioritizing card reprovisioning sequence. For example, the server may be configured to prioritize card reprovisioning. The first device may be subject to eligibility criteria. For example, after determination of the one or more security concerns, the first device may subject to a prioritized list associated with eligibility prior to receipt of the one or more commands-application protocol data unit. In some examples, the server may be configured to screen the first device based on at least one selected from the group of time elapsed since issuance of the card, card usage for transactions, transaction type, card type, one or more determinations of the security concerns associated with the first device, and/or any combination thereof. In this manner, the server may be configured to evaluate and rank how many first devices and which types of first devices may be configured to receive the one or more commands-application protocol data unit based on the eligibility criteria before signaling to the application of the second device to transmit the one or more commands-application protocol data unit. In one example, one or more sets of first devices may be prioritized to receive the one or more commands-application protocol data unit after the server is configured to determine whether the first device is a credit card and is associated with a notice of fraudulent charges. In another example, one or more sets of first devices may be prioritized to receive the one or more commands-application protocol data unit after the server is configured to determine whether the first device is an identification card that has been abnormally used, for example exceeding a predetermined threshold, for one or more transactions. In yet another example, one or more sets of first device may be prioritized to receive the one or more commands-application protocol data unit after the server is configured to determine how much time has elapsed since issuance of the first device. In these non-limiting examples, the server may be further configured to prioritize which of these determinations are to be made first, second, third, etc. In this manner, a designated number of first devices may be reprovisioned on an individual basis and/or in a batch. The first devices may also be reprovisioned on an as-needed basis, according to a predetermined schedule, and/or any combination thereof.

At block 620, the method 600 may include transmitting, via a communication interface, a command-application protocol data unit. In some examples, the application comprising instructions for execution on the second device may be configured to encrypt one or more keys. Without limitation, the second device may comprise an ATM, a kiosk, a point of sale device, or other device. The application may be configured to transmit the one or more encrypted keys. In some examples, the application may be configured to transmit one or more parameters. Without limitation, the one or more parameters may include at least one selected from the group of primary account number information, expiration date information, card verification code, and/or any combination thereof. In some examples, the one or more parameters may comprise dynamic information, such as changed personalization data including but not limited to card master keys, such as secret and public/private keys, and one or more spending limits. The application may be configured to transmit one or more commands-application protocol data unit including the one or more encrypted keys, the one or more parameters, one or more applet identifiers, and one or more instructions associated with a class of a header. In some examples, one or more session keys may be generated at the second device or server, which may be used to encrypt one or more master keys. In some examples, the application may be configured to transmit the one or more commands-application protocol data unit to the first device after one or more entries of the communication interface into a communication field of the second device.

The first device may be configured to receive the command-application protocol data unit including the one or more encrypted keys, the one or more parameters, one or more applet identifiers, and one or more instructions associated with a class of a header. In some examples, one or more session keys may be generated at the second device or server, which may be used to encrypt one or more master keys. For example, one or more limited use session keys may be generated based on a cryptogram and a counter to encrypt data. The first device may be configured to receive the encrypted data and decrypt it for storage. The one or more instructions may each be associated with a code, and include decrypting and/or confirmation of the one or more decrypted keys, storing and/or confirmation of the one or more decrypted keys.

The first device may be configured to receive the one or more commands-application protocol data unit. For example, the first device may be configured to receive the one or more commands-application protocol data unit from the application of the second device. The first device may be configured to decrypt the one or more encrypted keys. One or more applets of the first device may be configured to store one or more decrypted keys in a secure element. A first applet may be configured to transmit, via a communication channel, the one or more decrypted keys and the one or more parameters to a second applet.

At block 630, the method 600 may include changing an association from a first account to a second account. After decryption of the one or more encrypted keys, the first device may be configured to change an association from a first account to a second account. Moreover, the first device may be restricted to a predetermined usage after decryption of the one or more encrypted keys. In one example, the first device may be subject to one or more predetermined spending thresholds. In another example, the first device may be subject to a predetermined number of uses. For example, the first device may be used for only a designated set of transactions, such as for lunch only and/or for office furniture. In another example, the first device may be subject to a predetermined number of usages for one or more types of transactions, including but not limited to a debit card transaction or a credit card transaction.

In another example, the first device may be used for only transactions occurring during a certain time (e.g., business hours of 9:00 am to 5:00 pm), on certain days of the week (e.g., weekdays, weekends, only Mondays, only Thursdays and Fridays), of on a certain date (e.g., Wednesday, Jul. 1, 2020). In another example, the first device may be used only for certain purposes, such as for expense account purposes (e.g., travel expenses including airfare, meals, and hotels), for a designated project (e.g., a certain type of equipment or hardware needed for a project), with designated or approved merchants, or with a specified list of merchants known to offer goods or services needed for a particular purposes.

It is understood that the foregoing listings are exemplary and that any of these examples can be used in combination with one another. Thus, a user may use the same card configured for a variety of purposes and with a variety of accounts.

At block 635, the method 600 may include transmitting, via the communication interface, a response-application protocol data unit. The first device may be configured to transmit, responsive to the one or more commands-application protocol data unit, one or more responses-application protocol data unit. The one or more responses-application protocol data unit may include one or bytes indicative of a status of the command. For example, at least one of the one or more responses-application protocol data unit may be configured to indicate an execution status associated with the one or more instructions. The first device may be configured to transmit the one or more responses-application protocol data unit to the application of the second device. In some examples, the first device may be configured to return a successful execution status associated with the one or more instructions. To the extent that the execution status of the one or more instructions is not successful, the first device may be configured to return a warning or unsuccessful execution status.
